32.2.4.26 Endpoint Control Register n (USB_ENDPTCTRLn) (Non-EHCI)
There is an USB_ENDPTCTRLn register of each endpoint in a device. USB_ENDPTCTRL0 is used as a
control endpoint. The remaining endpoints are not used as control endpoints.
These registers are not defined in the EHCI specification.

TX Endpoint Enable. Endpoint zero is always enabled.

TX Endpoint type. Endpoint zero is always a control endpoint (00).
TX Endpoint Stall.
Software can write a 1 to this bit to force the endpoint to return a STALL handshake to the host. It continues
returning STALL until the software clears this bit or it is automatically cleared upon receipt of a new SETUP
request.
After receiving a SETUP request, this bit continues to be cleared by hardware until the associated bit in the
USB_ENDPTSETUPSTAT register is cleared.
Note: There is a slight delay (50 clocks max.) between the associated bit in the USB_ENDPTSETUPSTAT

register being cleared and hardware continuing to clear this bit. In most systems, it is unlikely the DCD
software observes this delay. However, should the DCD observe that the stall bit is not set after writing
a 1 to it, follow this procedure: continually write this stall bit until it is set or until a new setup has been
received by checking the associated bit in the USB_ENDPTSETUPSTAT register.
